Groundwater Contamination Investigation & Environmental Risk Assessment
Systematic groundwater pollution investigation using high-resolution characterization and quantitative risk assessment.
Engineering Background
When a landfill shows signs of groundwater contamination, or detailed investigation is mandated under the "Technical Guidelines for Groundwater Environmental Status Investigation and Assessment at Hazardous Waste and Landfill Sites," systematic detailed investigation and environmental risk assessment must be conducted. Objectives: identify contaminant species, concentrations, spatial distribution and temporal dynamics in groundwater; evaluate contamination origins and migration trends; and perform human-health and ecological risk assessments—providing a scientific foundation for pollution control and risk management.
- Liner integrity inspection (electrical / tracer / CCTV)
- Groundwater monitoring-well layout and sampling
- Hydrogeological conditions survey
- Numerical contaminant-transport modeling
- Contaminant fingerprinting and source attribution
- Human-health and ecological risk-assessment models
- Comprehensive investigation report with remediation recommendations
Principle & Method
Governing standards: GB 16889-2024 Article 7.9 mandates triennial liner-integrity inspection combined with periodic environmental risk assessment; plus Technical Guidelines for Groundwater Environmental Status Investigation and Assessment at Hazardous Waste and Landfill Sites; Technical Guidelines for Detailed Investigation, Management and Remediation of Groundwater Contamination at Landfills; and the Zhejiang Provincial Landfill Status Investigation Guideline. Investigation scope includes: source identification, contaminant-species characterization, plume survey (planar and vertical distribution with seasonal dynamics), migration and transformation behavior, diffusion forecasting, and risk assessment.
